Some users may see a blank page when using the links above. This
occurs because some browsers have problems with the new FIPS 140-2
validated encryption that is now mandatory on all federal systems.
Since access to the NCNR-IMS now requires the use of an Internet
Browser that is capable of TLS 1.0 encryption, users are advised
to refer to the following instructions:

Internet Browser Requirements

a) Microsoft Internet Explorer (IE) - version 6.0 or later is required. To check your version of IE, click Help | About.

Note: Some settings may be pre-set and cannot be changed. If so, then users should skip those settings and simply change
the settings that can be changed.

b) Mozilla Firefox - version 1.0 or later is required. To check the your version, click Help | About. There have been reports of
problems with FIPS compliance; if you see page errors (e.g. "Transmission Interrupted" error), please try upgrading Firefox or use IE.

Note: Some settings may be pre-set and cannot be changed. If so, then users should skip those settings and simply change
the settings that can be changed.

Please verify the following settings based on your operations system:

Windows - (Tools | Options)

Linux - (Edit | Preferences)

Mac - (Firefox | Preferences)

Enable JavaScript (Content tab)

Accept Cookies (Privacy tab)

Use TLS 1.0 (Advanced | Encryption)

After making changes, restart the browser.

c) Safari - no changes required.

Once the above settings have been set, you should be able to access the new URL by clicking on the link
https://www-s.nist.gov/NCNR-IMS (open in a new window)

If you see a blank page or don't see the NCNR-IMS application, then please contact Siddharth Khosla at
(301) 975-4640 or email us at ncnr_ims@nist.gov.
